    Abstract: A method and apparatus are disclosed from the perspective of a User Equipment. In one embodiment, the method includes the UE detecting and/or receiving downlink transmission in a first channel occupancy time in unlicensed spectrum. The method also includes the UE detecting and/or receiving downlink transmission in a second channel occupancy time in unlicensed spectrum, wherein the second channel occupancy time is a next channel occupancy time detected by the UE after the first channel occupancy time. The method further includes that after the first channel occupancy time ends, the UE performs receiving beam sweeping in each time unit until the UE receives downlink transmission in the second channel occupancy time or until the UE finds a candidate beam in the second channel occupancy time.

    Abstract: Methods and apparatuses for selecting beam for preconfigured uplink resources in a wireless communication system are disclosed herein. In one method, a user equipment (UE) receives, from a network node, a signaling to configure at least one Preconfigured Uplink Resource (PUR) associated with one or more beams from multiple beams. The UE selects a first beam from the multiple beams and performs a transmission of data in RRC_INACTIVE state using the at least one PUR via the first beam if the first beam fulfills at least one condition, wherein the at least one condition comprises that the first beam is associated with the at least one PUR and Reference Symbol Received Power (RSRP) of the first beam is better than a first threshold. The UE initiates a Random Access (RA) procedure and performs the transmission during the RA procedure if no beam of the multiple beams fulfills the at least one condition.

    Abstract: A slot antenna assembly adapted to a metal case is provided in the disclosure. The slot antenna assembly includes a substrate and a metal wire. The substrate includes a first sheet plate and a second sheet plate. The first sheet plate is conductive and is provided with a slot opposite to an opening of the metal case, a size of the slot being less than or equal to a size of the opening. The second sheet plate is not conductive and is connected to the first sheet plate. The metal wire is located on a surface of the second sheet plate to be connected to a feeding signal. A vertical projection of the metal wire on the first sheet plate crosses the slot, and the metal wire and the slot together excite a low-frequency mode and a high-frequency mode.

    Abstract: Control structures and techniques for transmission time interval (TTI) shortening in wireless communication systems are provided. Exemplary techniques can comprise establishing a UE device connection to a base station having a first TTI, wherein the UE device is configured to employ TTI shortening and has a second TTI different from the first TTI and monitoring a first short physical downlink control channel (PDCCH) region for a scheduled downlink (DL) transmission via the second TTI, wherein a time distribution associated with multiple second TTIs within the first TTI is determined based on a control format indicator (CFI) value indicated via the first TTI. Exemplary techniques can further comprise receiving a DL transmission via the second TTI and transmitting a hybrid automatic repeat request (HARD) acknowledgement (ACK) (HARQ-ACK) feedback on an associated UL channel for HARQ-ACK feedback, wherein for a number of DL transmissions via the second TTI within one of the first TTI on the associated DL, a number of associated UL channels for HARQ-ACK feedback occur within the same one of the first TTI on the associated UL. Further control structures and techniques for TTI shortening for wireless communication systems are described.

    Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE initiates a random access procedure. The UE receives a Physical Downlink Control Channel (PDCCH) transmission. The UE determines whether contention resolution associated with the random access procedure is successful. If the initiating the random access procedure is performed for Special Cell (SpCell) beam failure recovery, the determining whether the contention resolution is successful is based on whether the PDCCH transmission is addressed to a Cell Radio Network Temporary Identifier (C-RNTI) of the UE. If the initiating the random access procedure is performed for Secondary Cell (SCell) beam failure recovery, the determining whether the contention resolution is successful is based on whether the PDCCH transmission is addressed to the C-RNTI of the UE and whether the PDCCH transmission contains an uplink (UL) grant for a new transmission.
